A device for engaging and disengaging a line comprising a pair of pivotal arms turnable to an upright position and to a horizontal position and supported at a location close to a line engaging bitt opposed to and a distance away from a line guiding member, a pressing traverse arm extending between the free ends of the pivotal arms, a disengaging traverse arm extending between intermediate portions of the pivotal arms for disengaging the line from the bitt, apparatus for turning the pivotal arms to the upright position and to the horizontal position, and a pressing bed positioned to oppose the pressing traverse arm when the pivotal arms are turned to the horizontal position, the disengaging traverse arm being positionable above the bitt when the pivotal arms are in the upright position, the traverse arms and the pivotal arms defining a space for inserting the line therethrough. The line can be engaged with and disengaged from the bitt or bollard easily and properly. While the line is in engagement with the bollard, the pressing traverse arm presses the line against the bed. This eliminates the likelihood that the line will disengage from the bollard when the ship pitches or rolls and also permits use of low bitts or bollards. |
